PURPOSE: A missile warning radar system is provided to rapidly respond to threatened situations by previously generating warning. CONSTITUTION: A first mixer(105) adds the frequency of a pulse through a transmitter and the radio frequency(RF) generated from a first oscillator. A second mixer(110) subtracts the RF participated to the upward conversion of a transmission signal from the frequency of a signal through a low noise amplifier. A third miser(112) subtracts the second intermediate frequency participated in the upward conversion of the transmission signal from the frequency of a signal through an intermediate frequency amplifier. A signal converter(113) converts the intermediate frequency signal through the third mixer into a digital intermediate frequency signal. The digital signal is inputted to a digital signal processor(114) and verifies whether target is threatened based on a signal processing algorithm.
